    * A special type of JSF DataModel to allow a datatable and datapaginator
    * to page through a large set of data without having to hold the entire
    * set of data in memory at once.
    * Any time a managed bean wants to avoid holding an entire dataset,
    * the managed bean declares this inner class which extends PagedListDataModel
    * and implements the fetchData method. fetchData is called
    * as needed when the table requires data that isn't available in the
    * current data page held by this object.
    * This requires the managed bean (and in general the business
    * method that the managed bean uses) to provide the data wrapped in
    * a DataPage object that provides info on the full size of the dataset.
